SPEKTRUM DX18 • TRANSMITTER INSTRUCTION MANUAL

The Sequencer menu option provides this-then-that mixing with 
a time delay. Five different sequences (S1 through S5) are avail-
able to control 2 functions each (A and B), in 2 timing directions 
(forward or reverse). Sequences appear throughout function 
screens as assignable switches. 

CAUTION:  Always review the action of a sequence on 
the Monitor or X-Plus Monitor screen BEFORE operating 

the model to ensure controls act as desired. Failure to do so 
could cause a crash, resulting in property damage and or injury. 

You can program multiple functions to sequentially activate 
in response to an assigned switch. For example, an assigned 
Gear switch can open gear doors, lower the gear, then close the 
doors. In reverse, gear doors open, the gear retracts and the 
gear doors close. 
You can assign each Sequencer function to a switch in most 
Function screens such as Flight Mode, Dual Rate, Mixing, 
Throttle Curve, Pitch Curve, etc. 
You can assign several functions to a sequence to decrease 
the number of controls you need to touch during complex fl ight 
transitions, for example, applying your assigned dual rates and 
exponential when the landing gear deploys and the fl ight mode 
changes. 
If you select an S-Number-A sequence, for example, S3A, the 
sequence operates as a timed 5-position switch. An S-Number-
B sequence operates as a timed 3-position switch. The 5 
positions correspond to the sequencer values shown on the 
time delay graph in the second Sequencer screen. In a function 
screen, highlight each point (0-4) and select the switch position 
desired for a function to be active.  
When S1B (or another sequence-number-B) is selected as 
a switch in a function, the sequence will operate as a timed 
3-position switch. The 3 positions act as ‘kick points’ of the 
movement at fi xed percentages (equal thirds) of the sequencer 
output. In a function screen, highlight each point (0-2) and select 
the switch position desired for a function to be active.  

1. In the fi rst Sequencer screen, select 1 of the 5 available 

sequences.

2. In the second Sequencer screen, assign a switch to the 

sequence. We recommend using a 2-position switch. 

  Tip: If you need to use a 3-position switch, you must assign 

one direction to two adjacent switch positions, for example, 
0 and 1. Assign the opposite direction to the third switch 
position.

3. Assign the timing for the Forward and Reverse directions as 

desired. There is no delay when you use the Nor option. You 
may also select a delay time between 0 and 30 seconds.

4. Assign names for each sequencer function, as desired. 
5. Select either Step (S) or Proportional (P) for the Sequencer 

output.Step: The sequence only changes at kick points. 
Otherwise, there is a delay in the sequence until it reaches 
the next kick point.
Proportional: The sequence movement is proportional 
between kick points. The sequence maintains rate and 
direction until it reaches the next kick point.

6. Adjust the Sequencer motion percentages in the third screen.

For example, you may move points 1, 2 and 3 closer to the 
beginning of the sequence so the motion occurs earlier. This 
results in a delay between point 3 and point 4 at the end of the 
sequence.

The Sequencer function determines the response for channels 
included in the sequence. 
Refer to the Monitor screen to see how respective channels 
interact in the Sequencer.
